摘要
近年来,城镇化建设步伐不断加快,不透水的混凝土等硬面设施的使用使得城市的降水下渗量减少,这会增加城市河道和排水系统的排水负担。海绵城市是新一代城市雨洪管理的概念,其综合考虑了城市河道治理水工、排水以及生态等功能要求,利用材料的抗压、渗水、耐磨等优点增强城市的弹性和适应性,实现雨水的储存和净化,并能够在必要时进行释放重复利用,既能缓解城市的热岛效应,又能修复城市水生态,增强城市防涝能力,提高河道水环境综合整治效果。
In recent years,the pace of urbanization construction has been accelerating,and the hard surface facilities such as impermeable concrete have reduced the seepage amount under urban precipitation,which will increase the drainage burden of urban river channel and drainage system.Sponge city is a concept of a new generation of urban rain flood management,which considers the urban river treatment hydraulic,drainage and ecological function requirements,using the advantages of pressure,seepage,wear resistance to enhance the elasticity and adaptability of the city,realize rainwater storage and purification,and if necessary to release reuse,can alleviate the urban heat island effect,and repair the urban water ecology,enhance the urban waterlogging prevention ability,improve the river water environment comprehensive improvement effect.
